Science City, Kolkata

Science City in Kolkata is described as the largest science centre in the Indian subcontinent. It opened in 1997 and occupies a campus of 49.6 acres, with indoor halls, an outdoor park and a large auditorium for scientific and cultural events.

The Dynamotion Hall has optical illusions, a Powers of Ten display on the scale of the universe and an aquarium of 26 tanks, along with a live butterfly enclosure and a Science On a Sphere projection system developed by NOAA. The Earth Exploration Hall is a two-storey hemispherical building built around a giant split globe. In the Space Theatre a Helios star ball projects the night sky, and the Time Machine simulator offers virtual space flights.

Outdoors, the Science Park includes a gravity coaster, a monorail cycle and a maze. A Science Exploration Hall added in 2016 covers evolution, new technology and India's scientific history.
